Description of the invention (12) It is represented by only three control signals SO, S1, and S2. However, the control signals SO, S1, and S2 are different for each multiplexer. The operation of the clock tree structure of the semiconductor integrated circuit in this first embodiment will be described below. In this first embodiment, the multi-phase clock signals (: 1 ^ _eight to (: 1 ^ -11) can be passed through the multiplexer 1 * (: 101 to 1 ^ 108, ^^ 201 to MC216, and MC301 to MC316 Selective allocation to each segmented area Areai to Area 16 〇 Figure 9 shows multiple transmissions iVil 丄 U 丄 芏 MUi III V not used for clock distribution, ^ υ 1 to MC216, and control signals s0, S1, and MC301 to MC316 The relationship with S3 and the clock signals assigned to the divided areas Areai to Areai 6 on the chip. However, Figure 9 only shows the control of the multiplexers MCI 01 to MCI 04, MC201 to MC2 04, and MC3 01 to MC3 04 Signals s0, S1, and S3, and the clock signals allocated to the divided areas Areai to Area4. Although the control numbers 30, si, and S3 are "00", the multiplexers MC1 〇1 to MCI 08 The clock signal cu-A is selected and outputted. Similarly, when the control signals S1, S1 and ^ are both " 〇〇1 ", the multiplexers MC101 to 1 ^ 108 select and output the second day = signal CLK_B, # When all of them are " 〇1〇 ", the clock is selected and outputted. Λ: When all are " 〇11 ", the clock signal M is selected and outputted; ® 'are all 1 〇 When "" selects and outputs the clock signal CLK-E, when ^ Λ / Λ is hungry K-F when both are " 1Q1 ", when they are both, select and output the clock signal CLK_H. For m output:: 0: ", MC201 · 16 selects and combines the example and a. In the case of MC201, the wheel of MclO1 556344 V. Invention description (13)) Similarly, when the control When the letter MC216 selects and outputs the second white, it is 1021 to the middle, and the round of MII02 comes out. When J enters in the case of _! (For example, when MC2H white / 10, it selects and outputs the second In the case of ||, the output of MC104). 11 in (for example, in MC201 and when the control signal S. is " 丨 " then select and: brother MC two out) In the case, MC2 0 2). Therefore, if the values of the control signals, S1, and S3 of each of the multiplexers MC101 to Rainbow 104, MC2101, and MC3IH dirty 3G4 are set to = not shown in Figure 9, the clock signal CLK-A or [C can be selectively assigned to the division domains Areal and Area2, and the clock signal CLK — (^ tCLK_D can be selectively assigned to the division domains Area3 and Area4. Similar control can be performed on other multiplexers MC105 to MC108, MC20 5 to MC216, and MC3 0 5 to MC316. Therefore, the multi-phase clock signals CLK_A to CLK_H can be selectively assigned to the divided areas Area5 to Area6 〇 It should be noted: which of the multiphase clock signals CLK_A SCLK_H The number of divided areas allocated is determined by the specifications of the semiconductor integrated circuit. Then, the setting of the control signals SO, S1, and S3 is performed on the wiring after the sequence circuit unit 2 and the combination circuit unit 3 are formed on the wafer. In the step, that is, the wiring pattern connected to the power supply is formed to set the value of the control signal to π 1π and is connected to the ground.

Description of the invention (15) The potential of the input terminal CB and the output terminal 0 of the stage gate INV3 does not change as shown in Figure 2HB. Therefore, the switching operation based on the clock signal CLK will not be implemented. The load of each multiplexer MC301 to MC316 is the first-stage gate of the clock input section of the sequential circuit element 2. Therefore, if the sequence circuit unit 2 is assigned to each of the multiplexers MC301 to MC316, the number of gates connected to each of the multiplexers MC301 to MC316 is equal to each other. Therefore, the load of MC3101 to Hua316 of $ work is equal to each other without any floating =. In addition, in this first embodiment, it is designed so that the wiring is not between the output terminal of the first-stage gate of the clock input section of the remaining sequential circuit unit 2 and the input terminal of the next-stage gate that will not be used. Therefore, in this remaining sequence circuit unit 2, the inverter INV3 and the diagonal lines in FIG. 12 are drawn, and the gates TG1 to TG4 become unloaded transistors. Therefore, compared with the conventional semiconductor integrated circuit in which all sequential circuit units become loads regardless of their use, power consumption can be reduced. It should be noted that in this first embodiment, the number of phases of the clock signal is designed to be eight, the number of input signals of the multiplexer random 101 to red 108, 1 ^ 201 to 1 ^ 216, and MC301 to MC316 are respectively It is eight, four, and two. The number of levels of the clock tree is three and the number of divided areas on the chip is; six: Of course, the number is not limited to the foregoing value.

Description of the invention (21) The sequence circuit unit 2 in person ^ 313 to person 1 ^ 316 in the segmentation field is compared. Therefore, the multiplexer uses 313 to 316 or multiplexer MC213 ^ to enable the terminal M to be set to " 0 ". Then, the aforementioned terminal terminals EN are all set to "1". | ~ The enabling terminal EN is fixed by connecting the wiring pattern to the enabling terminal ⑽. If the enabling terminal EN is set to "1", then Wiring pattern connected to company 0 reactor. If it is set to " 〇 ", then: "= wiring pattern of the surface. As described above, in the third implementation, stop distributing the clock signal to the The segmentation field composed of the product f circuit is used to stop the non-obedience. The circuit unit 2 is made. Therefore, compared with the conventional technique Π:;?; :::, the operating power consumption can be reduced, similar to the first implementation For example, the electricity of the + conducting volume circuit is as described above. According to the present invention, the sequence electricity: the internal cores alternately arranged on the semiconductor wafer are connected with a plurality of selection driving elements connected in a tree shape, and a phase clock is installed. The signal is divided into multiple division areas by dividing the internal core and then selectively dividing each other. Then, each of the plurality of selection areas is arranged on the semiconductor wafer and connected to form sequential circuit units in each division area. Part = The input terminals are equal to each other. Therefore, a clock with the same load and wiring length as the wiring length can be used, the bit clock signal, and the load is skewed from the clock. &Amp; so 'can reduce the sequence circuit Also 'order The circuit unit includes a first gate element, which is provided in the fifth, description of the invention (22), a clock input unit, and a second circuit. The sequential circuit unit is connected between the second logic, which makes The output terminal and the second logic are free :: == in the first logic interval: to the sequence circuit Cuiyuan '= ,: and for the placement of the unused wheel output terminal and the second logic gate element Diyi logic gate = the input terminal of the idle element is connected to the power supply for J = between 'and the second, the loss can be reduced to the minimum, while the second dimension power = electricity, and the sequence circuit unit includes the load structure of f. The first stage The clock input unit is used to energize the first closed element, and is determined based on the multi-phase clock signal. The output potential is fixed: regardless of the output power through the energization signal; and the second The logic gate element, the output terminal of the selected multi-phase clock signal gate element, is connected to the first logic word by two or two round-in terminals. The enable signal is set so that the first series i is used: sequence circuit unit and Sequential circuit board that will be used The first logic element becomes the second state, the second logic element becomes the second state, the energization signal is set to the second circuit consumed by the used sequential circuit unit. Since the H can be reduced, the power is not minimized, and the same negative power is maintained. The loss of consumption can be reduced. If one of the two optional drive elements in the segmented field downstream of the plurality of selected drive elements is selected to drive the element to prevent the transmission circuit units of the selected drive element from being unused, Design the power consumed by the sequence circuit unit 7 and therefore, reduce the unused power while maintaining the same load structure. The loss of power consumption can be suppressed to the maximum on page 28. M6344 The diagram simply illustrates the master chip type shown in the flat display.
